N2 - The use of simplified modal analysis methods for the modal analysis of bridge decks contributes to the intelligent modelling process for the analysis of the dynamic behaviour of bridges opening the way to easily feed a Digital Twin (DT) accelerating the demands of the Decision Support System (DSS) in real time. This work presents a novel method that allows the modal analysis of bridge decks by applying a formulation that reduces the structural problem to a reduced number of degrees of freedom associated with the structural response mechanism mobilised in the bridge deck vibration. A parametric study is proposed to analyse the dynamic structural response of a total of 20 bridge decks of different lengths and number of spans. The proposed method is experimentally tested by a dynamic loading test of a full-scale railway bridge deck. As a result of the analysis, the proposed method reflects an adequate convergence with the experimental dynamic structural response.
